S.T.A.L.K.E.R.: Shadow of Chernobyl

The Ukrainian town of Chernobyl was the site of a severe nuclear accident in 1986. In an alternate timeline, following attempts to repopulate the area, another unexpected accident occurred twenty years later. By the year 2012 the area, which was dubbed "Zone", has become hazardous with mutated animals, bandits, and mysterious anomalies. These anomalies differ in their effects, but they all have one thing in common - they are deadly. Despite that, the Zone attracts scientists, explorers and scavengers (known as "stalkers") hunting for valuable artifacts. Military organizations have been formed, fighting for dominance in the Zone.

The player controls a stalker who has lost his memory in an accident. After being rescued by another stalker, he discovers himself in a village located on the outskirts of the Zone, with only a single clue: he has a note in his PDA telling him to kill an unknown person with the nickname "Strelok".

S.T.A.L.K.E.R.: Shadow of Chernobyl is inspired by the science fiction novel Picnic on the Roadside (1977) by the Soviet Russian authors, the brothers Arkadi and Boris Strugatsky. The game is an open-ended first-person shooter featuring a thirty square kilometer playing area which the player is free to explore. There are also many characters the protagonist can communicate with; in this sense the game has similarities to RPGs, although there are no attributes or skills to improve. The protagonist may also develop relations with NPCs. Helping a faction will boost his reputation with it, which may result in better items for purchase or information, while attacking a member of said faction will ruin his reputation and prompt other members to attack him. Along with the main quest, the player can also complete side quests, some of which have time limits.

The player has to carefully manage the protagonist's inventory, not only because there is a carrying capacity, but also because weapons and armor degrade as they are used. The player can also use artifacts, which can be usually found near anomalies, to his benefit. Artifacts offer different kinds of bonuses, but often have negative side effects: for instance, an artifact could improve the hero's bullet resistance but also increase his radiation level.

The game features ragdoll physics, destructible surroundings, HDR lightning, dynamic weather, day and night cycles, and multiplayer for up to 32 players.
